It appears that Mauricio ‘Shogun’ Rua’s first light-heavyweight title defense against Rashad Evans will have to be put on hold due to yet more problems with the Brazilian fighter’s knee.

Rua has already had two operations on his knee since joining the UFC in 2007, and Dana White revealed to MMAJunkie that after his first round victory over Lyoto Machida at UFC 113, he again required treatment.

“He just got out of the hospital; it was a successful surgery,” White said. “He had the surgery in [Los Angeles], and he’s going to be doing all his therapy in (Las) Vegas.”

White admitted that he did not know when Rua would be fully recovered, but said that he’d spend the next five weeks in Vegas.

Shogun himself has so far not spoken publicly about his latest surgery.
